Способ применения каррирования в js

carry.js

Function.prototype.partial = function(){

	var fn = this, args = Array.prototype.slice.call(arguments)
	return function(){
		var arg = 0
		for (var i = 0; i < args.length && arg < arguments.length; i++) {

			if(args[i] === undefined) {
				args[i] = arguments[arg++]
				return fn.apply(this, args)
			}
		}
	}
}
// example 

var delay = setTimeout.partial(undefined, 10000)

delay(function(){
	console.log('after 10 sec')
})
